    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 8a 8a:d  
    z9IW&f~~P  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: gq+0t  
    enableservice('AutomationServer', true) 'e]>lRZ  
    enableservice('AutomationServer') qX\85dPn@}  
    u~uz=Yse  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 q]: 72+  
    79>x/jZka  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: H6`k%O*  
    1. 在FRED脚本编辑界面找到参考. / Q@4HV  
    2. 找到Matlab Automation Server Type Library w~Q\:<x&~Z  
    3. 将名字改为MLAPP R4;1LZ8XzS  
    LAk .f  
    I= :yfW  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 agwbjkU/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )x\%*ewY  
    1. 创建Matlab服务器。 tZ62T{, a  
    2. 移动探测面对于前一聚焦面的位置。 E8kD#tL  
    3. 在探测面追迹光线 9{fP.ifdv7  
    4. 在探测面计算照度 BEb?jRMjLg  
    5. 使用PutWorkspaceData发送照度数据到Matlab Qc*p+N+$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `?=3[  
    7. 用Matlab画出照度数据 JzN "o'  
    8. 在Matlab计算照度平均值 hJ8&OCR }  
    9. 返回数据到FRED中 LI}e_= E
